SEED SOWlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 653,197, dated July 3,1900. Application filed May 11,1898. $erial No. 680,422. (No modeL) T0at whom it may concern:

Be it known that 1, JOHN GREEN, a citizen of the United States, residingat 22 Mill Lane, Treeton, county of York, England, have invented new anduseful Improvements in Seed- Sowing Machines, of which the following isa specification.

My invention relates to improvements in or connected with machines forsowing seed, and has reference to those machines in which a revolvingcylinder having depressions in its periphery is employed at the bottomof a hopper, from which the said depressions receive in rotation acertain quantity of seeds contained in the hopper and discharge them onthe land.

The objects of my invention are, first, to provide a more simple meansof regulating and distributing the seeds, and, secondly, to dischargethem at regular distances apart without in any way destroying or causingthem to jam in the depressions. I attain these objects by the mechanismillustrated in the accompanying drawings, in which- Figure 1 is a planof the entire machine. Fig. 2 is a front elevation of machine. Fig. 3 isa side elevation of machine. Fig. 4 is a part of side elevation insection showing recesses and adjustable sliding regulating-plate bymeans of which the distribution of the seed is accomplished.

Similar letters refer to similar parts throughout the several views.

According to my invention I employ a carriage in which the Wheels arefastened to the axle, so that when the wheels rotate the axle rotateswith them. On or about the said axle I mountone or more drills insuitable number to sow the seed, each drill consisting of a cylinderhaving one or more sets of recesses in its surface. Around theseed-cylinder a hopper is provided, from the back of which the recessesin the cylinder take the seed. The base of the hopper is connected tothe upper part of a spout, and as the cylinder revolves in the hopperthe seeds fall into the recesses and are carried over and droppedintermittently on the land. The distance between the seed is controlledand regulated by a close-fitting sliding regulating-plate, which may beset so as to cut off one or more sets of recesses from access to theseed in. the hopper. A share is attached to the carriage in front of thespout of the hopper in such a manner that a furrow is cut into theground for the seed to fall into, and behind the spout two shares areprovided for the purpose of closing in the furrow after the seed isreceived. To cover and securely plant the seed,

a suitable roller may be placed behind the shares.

Any number of drills may be constructed on one machine and theadjustable sliding regulating-plates so connected that they may beactuated through the medium of one or more levers.

The recesses in the cylinder may be made of different sizes to suit thesize of the seed 'to be sown and the distance between them made tocorrespond to the size of the wheels, allowing the seed to be sown in-aregular manner and at suitable" distances apart.

The upper part of the framework a and the draft-poles b are connected tothe upright portion of the framework 0 at the back by hinges d (see Fig.3) and to the front by means of a sliding joint e, in conjunction with aspiral springf. (See Fig. 3.)

The above may be said to constitute the whole of the framework and iscarried by the wheels 9 and the ridge-rollers h. (See Figs. 2 and 3.)The framework is fastened to the axle of the wheels by two strongsemicircular straps on the under side of the draft-poles. The wheels 9and the seed-cylinder 7c are fastened to the axle in the followingmanner: theformer by lock-nuts z' and the latter by keys j. (See Fig.4..)

The seed-cylinder 7t and the sliding regulating-plate m (see Fig. 4) fitclose up to the back of the hopper n, so close that theZsmallest seedcannot work through into the spout of the hopper but only through itsproper medium-the recesses in the cylinder- -the peculiar arrangement ofwhich will be noticed. These recesses are placed on lines parallel withone another, but they themselves are not parallel with nor opposite oneanother; The first set (marked as 1, see Fig. 1) are placed at equaldistances apart and represent the maximum distance at which seed is tobe sown. The second set (marked as 2) is of the same pitch as 1, but areplaced so-that they fall halfway between any two consecutive recesses online 1. The third set is half the pitch of sets 1 and 2, and therecesses are placed so that they fall half-way between the recesses onlines 1 and 2. When the machine is not in use, the regulating-plate mcovers the whole of the recesses. When it is desired to sow seed, theregulating-plate m is drawn backward or forward, as the case may be, bythe regulating-plate lever 0, so that the recesses can have access tothe seed in the hopper n, the distance between the seedssown beingdependent upon the number of sets of recesses exposed. For example, ifone set only is exposed, the maximum distance will be sown. If one andtwo only, then one-half the maximum distance will be sown. If one, two,and three, then one-fourth of the maximum distance will be sown. It willbe seen that by placing more sets of recesses on the cylinder, andarranging them in the same mathematical order, a much less distance canbe sown.

The hopper n is divided into two portions by means of a vertical plate19, fastened onto regulating-platem. (See Fig. 2.) The back of thehopper restson the back part of the framework, is supported by the axle2' in the center, and is prevented from tilting over in front of themachine by theinclined bar 0". Fig.

The seed-cylinder 70 may be taken offiand a fresh one put on (whenrequired to sow a different kind of seed) at any time by unscrewing thelock-nutsz' and taking the keys j out.

I am aware that prior to my invention various patents have been grantedin which the cylinders and recesses in them are fed from a hopper abovethem. I therefore make no claim to such a combination.

Having now described and ascertained the nature of my invention and inwhat manner the same is to be performed, what I claim, and desire toprotect by Letters Patent, vis

In a seed-sowing machine of the class-described, the combination of ahopper with a seed-distributing cylinder is provided with recesses l and2 of the same pitch but not in the same axial line of the cylinder, andwith another series of recesses of a different pitch around theperiphery, means for rotating said cylinder, a sliding plate 717., andmeans for operating same, a conducting-spout, share for opening furrowin ground and means for closing said furrow upon the deposited seedsubstantially as set forth.
